— SERVICE 04 · Facade waterproof coating

Drone-applied facade coating.

Cleaning and coating in one engagement — 5–10 years of added facade life

Drone-mounted coating equipment applies a nano-scale hydrophobic layer directly after facade cleaning. Water-repellent, dirt-resistant and UV-stable, it suppresses mineral staining and tile delamination — the single most consequential protective step after a facade is cleaned.

— 002 · Where it applies

Four building types.

From residential towers to industrial facilities, the nano coating is formulated to the substrate, giving the facade long-term protection.

RESIDENTIAL

Residential towers

Communities of 20 storeys and above, and glazed residential buildings. Coating sharply reduces water tracking, moss and rain-wash streaking, so the facade holds its appearance three to five times longer.

#Residential communities#Curtain wall#Tiled facades
5–10 yrs added life
COMMERCIAL

Commercial offices

Office towers, hotels and department stores. The coating is self-cleaning: rainfall carries dust away, reducing how often the building needs washing and what maintenance costs over time.

#Office towers#Hotels#Retail
Lower maintenance cost
INDUSTRIAL

Industrial facilities

Plant envelopes, chemical storage tanks and stack structures. Resistant to acid rain, salt and chemical attack, preventing corrosion, coating delamination and loss of structural service life.

PUBLIC

Public buildings

Schools, hospitals, sports venues and stations. Operations continue during application, and a whole building is coated within one to three working days.

— 003 · Formulations

Three professional coatings.

Selected by substrate, budget and project scale. Every coating has passed UV, weathering and environmental testing, and has been bench-tested for compatibility with our drone pumps.

Formula 01
First choice

Water-based silane penetrant

★★★★★
Technical characteristics
Viscosity
1–5 cP (near water — ideal for drone pumps)
Particle size
Molecular (< 1 nm), zero clogging risk
Penetration depth
5–15 mm
Cure profile
Touch dry 2–4 h, full cure 24–48 h
Drone suitability
Pump compatibility
★★★★★
Water-based, non-corrosive to metal components
Atomisation
★★★★★
Low surface tension, even atomisation
Storage stability
★★★★★
Ambient storage, no settling
Application window
★★★★
Avoid rain, but tolerant of moderate wind
Recommended products
  • SOS nano water-based repellent
  • Wacker Silres BS 1701 (Germany)
  • Duo Yi De ALL Clean
Formula 02
Balanced

Low-viscosity polysiloxane emulsion

★★★★
Technical characteristics
Viscosity
8–20 cP (higher, still sprayable)
Solids content
15–25%
Coverage
Better than pure silane
Durability
7–12 years
Drone advantages
  • ·Drift resistance: heavier emulsion particles reduce wind carry
  • ·Adhesion: forms a very thin protective film
  • ·Tolerance: less sensitive to substrate moisture content
Application parameters
  • Dilution — concentrate : water = 3 : 1
  • Spray pressure — 2.5–3.5 bar
  • Flight speed — 2–4 m/s
  • Overlap — 40–50%
Recommended products
  • Evonik Protectosil CHEM TECK 40 (Germany)
  • Dow Corning 1-2577 siloxane emulsion
Formula 03
Economical

Modified acrylic water-based repellent

★★★★★
Technical characteristics
Viscosity
5–15 cP (adjustable)
Film formation
Semi-permeable film
Cost
Most economical
Colour
Tintable, to match stone tones
Where it fits
  • ·Budget-sensitive projects
  • ·Marble needing light tinting
  • ·Buildings on a frequent maintenance cycle
Limitations and cautions
  • Breathability — slightly below silane
  • Durability — 5–8 years
  • Viscosity control — dilution must be mixed on site

— 004 · Application process

Five steps to handover.

Cleaning and coating delivered in one engagement. A whole building takes one to three working days, with no disruption to occupants.

01
On-site survey

An engineer attends to confirm substrate, area and site conditions.

1 day
02
Formulation recommendation

Coating specified to substrate and environment, with an itemised proposal.

3 days
03
Facade pre-cleaning

Drone pressure washing to remove soiling, moss and grease.

1–2 days
04
Coating application

Drone-mounted spray equipment applies the coating evenly, zone by zone.

1–3 days
05
Sign-off and warranty

On-site sign-off, warranty certificate issued, and maintenance guidance provided.
